Anime exclusive

The protagonist of the series. A polite and humble boy who is the sole survivor from Ulley Village, which was destroyed by Physis-infected monsters. He is inducted into Granseed Academy by Faria after she saves his life and he bonds with the soul of a Knight, who is later revealed to be Jenius. He is later revealed to be a homunculus created by Amis Germain in an attempt to turn him into the Son of Destruction, destined to bring about the arrival of the God of Destruction. However, the spirit of Jenius inspired the homunculus to escape to a human town, where he killed a boy named Nemo, assumed his form and stole his memories. He is lethally injured by a corrupted Gareth but Ellen saves his life and he is visited by the spirit of the original Nemo, who forgives him for his own death and motivates him to protect the people he cares about. His weapon is a gauntlet grappling hook connected to a blade, which he can turn into Jenius' most powerful weapon, the Legis Breaker, an energy cannon with enormous destructive power. In his final battle with Sophitia, he remembers that the original Nemo actually sacrificed his life to save him, and the homunculus devoured him and assumed his form as a way to honor him. He and Jenius combine the last of their powers to recreate the Book of Time and trap Sophitia and the powers of darkness within it yet again, at the cost of completely extinguishing Jenius' soul and rendering Nemo a powerless human. Even without his powers, though, Nemo decides to remain by Faria's side and they embark on a journey in order to find a way to destroy the Book of Time and prevent its misuse.

Her weapon is a double-bladed axe spear. She saves Nemo's life and welcomes him to Granseed to begin his training as a warrior. She is very serious and dedicated to her work, but she is can also be friendly and warm whenever she isn't concerned with her duty. Her feelings for Nemo grow to the point that she is willing to risk her own life to prevent his execution, based on false evidence. She becomes infected by the power of destruction sealed within Granseed's old library in her attempts to save Nemo, but she doesn't care, as she has decided to protect Nemo by her own free will. She helps Nemo fight Sophitia, the true leader of Physis, and bears witness at how Nemo recreates the Book of Time and traps Sophitia within it, at the cost of losing his Succession powers. With the dark power sealed, Faria is freed from her curse and she reaffirms her desire to stay by Nemo's side. She resigns her position at Granseed and joins Nemo in a journey in order to find a way to destroy the Book of Time and prevent its misuse.

Faria's personal valet and member of the new Seven Knights. Her soul is bonded to that of Vanessa and she has the power to predict the future and manipulate the flow of time. Since childhood, she had trouble making friends before meeting Faria because she unwittingly predicted their deaths, to the point she believes she predicted the date of the end of the world, as she could no longer see the future beyond that point. She knows that Shirley is a vampire and has been allowing her to drink her blood in order to satiate her thirst. In the battle against Amis Germain, she nullifies his powers using temporal magic, a feat that leaves her physically exhausted. Fortunately, she had safeguarded a portion of the sand used by the silver hourglasses, mystical artifacts that can control the flow of time, and uses it to save Nemo's life, but this act nearly kills her and in order to save her, Shirley turns Ellen into a vampire.

Guilt-ridden, he promises to hunt down her killer. While his fellow Knights attack Physis' main fortress, Gareth investigates Granseed's old academy and finds it infested with Physis monsters. After defeating the monsters, he receives information from Sophitia about the old library. Upon learning about Nemo's origins, he orders his arrest and even becomes tempted to kill him but ultimately decides to his wait to be decided by the proper judgment. Unfortunately, the dark power sealed within the old library threatens to cause a global disturbance, causing an enraged Gareth to ask Sophitia to give him the power to kill Nemo, believing him to be the cause of the disaster. Gareth becomes corrupted by Sophitia's power and lethally injures Nemo before being seemingly killed by Sophitia herself. Thanks to his powers over darkness, however, Gareth survives and helps his fellow Knights defeat Sophitia and defend Granseed as a form of atonement for his previous betrayal. After the final battle, he makes a full recovery and rejoins his friends.

Member of the Seven Knights, bonded to the soul of Spike. He is obsessed with physical strength and constantly trains to become strong after his father died fighting Physis-infected monsters. He has a crush on Sophitia, who seduces him in an attempt to use him for her goals. He is corrupted by Sophitia's power, forcing Gildan to fight him.

When Reda reveals that Sophitia is part of Physis, Gildan is forced to fight Joe, who has been corrupted by Sophitia's power. Fortunately, he is able to bring Joe back to his senses and both help in defending the school against Sophitia's destructive power.

President of Granseed's disciplinary board and member of the Seven Knights, bonded to the soul of Rachel Agni. She is a vampire hailing from a family of pacifists that never harmed humans. Unfortunately, her family was killed and she was forced to escape to Granseed for her own safety. Only Ellen and Nemo know about her true identity and allow her to drink their blood as a form of friendship. Shirley is later implied to develop feelings for Ellen beyond the need to drink her blood. Her weapon is a rapier. Although vampires are naturally vulnerable to fire, Shirley developed some resistance to it thanks to her bond with Rachel. When Nemo's true identity as a homunculus is revealed, she is conflicted about her feelings on the matter until she decides to help Gildan vouch for Nemo's innocence. When Reda reveals that Sophitia is part of Physis, she agrees to take part in the effort to stop Sophitia. She is aware of Ellen's time magic and that it drains her life force every time she uses it, so she makes Ellen drink a portion of her blood to turn her into a vampire and save her life.

Member of the original Seven Knights. He bonded his soul to Nemo, granting him a suit of armor equipped with a hook-blade and an energy cannon. According to legend, Jenius sold his soul to Physis and set Granseed's old library on fire before being killed by Yunomia, but this was a fabrication. In reality, Jenius created the Book of Time, a special seal around the library to prevent the power of destruction from spreading across the world, and only allowed the lies about him to be remembered because the book's seal was imperfect. His spirit endured, however, and inspired the homunculus Nemo to escape from Amis Germain's base. For the most part, Jenius does not speak freely to Nemo, only speaking him during critical moments. In the final battle against Sophitia, the true leader of Physis, he and Nemo combine the last of their power to recreate the Book of Time, at the cost of completely extinguishing Jenius' spirit.

Member of the original Seven Knights and Faria's ancestor. She gifts Faria with the power of electricity. According to legend, she is the one who killed Jenius after he burned Granseed's old library to the ground before dying in battle herself, but this was a fabrication. In reality, she witnessed Jenius create the Book of Time in order to prevent the power of destruction from spreading and only allowed the lies about Jenius to be remembered because the seal on the Book of Time was imperfect. Even in her spirit form, she is infected with a curse that crystallized part of her right arm. She agrees to help Faria discover the truth about Jenius and the old library but warns her that Faria's life will be in danger, as well.
